二、 JavaMail是官方的 Java mail API，可參考 http://java.sun.com/products/javamail/。雖然該API比 sun.net.smtp.SmtpClient更豐富或者說更復雜，但它是可移植的。這里重新創建了一個 MailSender類，它包含了 JavaMail API。如下所示：
// ms_ prefix is for MailSender class variables // str prefix is for String // astr prefix is for array of Strings // strbuf prefix is for StringBuffers, etc. public MailSender( String strFrom, // sender String[] astrTo, // recipient(s) String[] astrBCC, // bcc recipient(s), optional String strSubject, // subject boolean debugging) { ms_strFrom = strFrom; // who the message is from ms_astrTo = astrTo; // who (plural) the message is to ms_debugging = debugging; // who (plural) the message is to
// set the host Properties props = new Properties(); props.put(\&;mail.smtp.host\&;, ms_strSMTPHost);
// create some properties and get the default Session Session session = Session.getDefaultInstance(props, null); session.setDebug(ms_debugging);
try { // create a message ms_msg = new MimeMessage(session);
// set the from InternetAddress from = new InternetAddress(strFrom); ms_msg.setFrom(from);
// set the to InternetAddress[] address = new InternetAddress[astrTo.length]; for (int i = 0; i astrTo.length; ++i) { address[i] = new InternetAddress(astrTo[i]); } ms_msg.setRecipients(Message.RecipientType.TO, address);
// set the bcc recipients if (astrBCC != null) { address = new InternetAddress[astrBCC.length]; for (int i = 0; i astrBCC.length; ++i) { eh.dbg(\&;astrBCC[\&; + i + \&;] is: \'&; + astrBCC[i] + &;'\&;); address[i] = new InternetAddress(astrBCC[i]); } ms_msg.setRecipients(Message.RecipientType.BCC, address); }
// set the subject ms_msg.setSubject(strSubject);
// set up the string buffer which will hold the message ms_strbufMsg = new StringBuffer();
